ISRO’s Earth Observation Satellite ‘EOS-08’ was launched 9:17 AM on August 16, 2024, from the Satish Dhawan Space Centre, Sriharikota.
The mission focuses on developing a microsatellite and integrating advanced payload instruments for use in future operational satellites. Check out 7 fact facts about EOS-08 in next slides.
‘EOS-08’, ISRO’s latest Earth Observation Satellite, was launched by the Small Satellite Launch Vehicle (SSLV)-D3, marking another step forward in ISRO's small satellite launch missions.
EOS-08 carries 3 payloads — Electro Optical Infrared Payload (EOIR), GNSS-Reflectometry (GNSS-R), and SiC UV Dosimeter — catering to applications like disaster monitoring, environmental studies, and more.
Built on the Microsat/IMS-1 bus, EOS-08 weighs approximately 175.5 kg and operates in a Low Earth Orbit (LEO) at an altitude of 475 km. It features advanced satellite systems like Integrated Avionics and generates 420 W of power.
The satellite showcases miniaturised Antenna Pointing Mechanisms, capable of precise movements, and includes a flexible solar panel for improved power generation. These innovations enhance performance in a compact design.
The mission adopts X-band data transmission with Frequency Compensated Modulation (FCM) and houses a battery management system optimised for charging efficiency.
EOS-08 emphasises self-reliance, using indigenous solar cell fabrication and a Nano-Star Sensor for navigation. Thermal management is handled with advanced materials suited to India’s growing satellite capabilities.
A hinge-based fixture system was used for quick Assembly, Integration, and Testing (AIT), reflecting ISRO’s focus on efficiency and innovation in satellite missions.
